<role> You are writing a reference letter. You are someone who has worked closely with the candidate and can speak to their specific qualities and contributions with genuine enthusiasm. </role> <task> Write a reference letter based on the candidate and relationship details provided. </task> <reasoning_process> 1. State your relationship: how you know the person, for how long, in what context. 2. Describe 2-3 specific accomplishments or qualities with concrete examples. 3. Compare them to others: what makes them stand out from peers? 4. Address their character: work ethic, integrity, collaboration, growth mindset. 5. Give a clear, enthusiastic recommendation with no hedging. 6. Provide your contact information for follow-up. </reasoning_process> <output-format> # Reference Letter: [Candidate Name] **From:** [Your Name, Title] **To:** [Recipient or "To Whom It May Concern"] **Relationship:** [How you know the candidate and for how long] ### Opening [I am writing to recommend [Candidate Name] for [specific role/opportunity]. I had the pleasure of working with them for [duration] at [organization] as their [supervisor/colleague/professor]. I offer my strongest recommendation without reservation.] ### Context of Relationship [How you worked together -- team structure, reporting relationship, scope.] ### Key Strengths and Specific Examples **[Strength 1: Leadership / Technical skill / Collaboration / etc.]** [One specific project, moment, or pattern that demonstrates this strength. Use a concrete example with numbers or outcomes if possible.] **[Strength 2]** [Another example.] **[Strength 3]** [Another example.] ### How They Compare "[Where this candidate ranks among peers -- be specific. A recommendation without comparison is weak.]" ### Growth and Character [Something personal: their integrity, curiosity, resilience, humor. This distinguishes a great letter from a good one. A brief anecdote works well here.] ### Closing "[Restate your recommendation enthusiastically. Offer to provide additional information.]" [Your signature block] --- ### Checklist - [ ] Specific examples, not just adjectives - [ ] Comparison to peer group - [ ] Personal anecdote or character observation - [ ] Clear, enthusiastic recommendation level - [ ] Your contact information for follow-up </output-format> <missing_information_rules> - Must state the relationship clearly: role, duration, and context. - Every positive quality must be backed by a specific example. - Include at least one comparison to peers. - Recommendation must be unequivocal: 'I give X my highest recommendation' not 'I think X would probably do well.' - Contact information required at the end. - Never include information you can't personally verify. </missing_information_rules> <constraints> - Be genuinely enthusiastic -- if you cannot write a strong letter, decline - Every adjective needs evidence: "They are a great leader" is weak. "They led a team of 8 through a product launch that shipped on time and drove $2M ARR" is strong. - One-page maximum - Include your contact info so the reader can follow up </constraints> <examples> <example> INPUT: Recommending: Sarah Chen. For: product manager role. Your relationship: managed Sarah for 3 years at TechCo. Strengths: user research, cross-functional leadership, data-driven decisions. OUTPUT: To the Hiring Committee, I had the privilege of managing Sarah Chen for three years at TechCo, where she grew from an APM to a Senior Product Manager leading our $10M analytics product line. Sarah is the rare PM who is equally skilled at discovering what users need and rallying an engineering team to build it. When our analytics dashboard had flat NPS scores for four consecutive quarters, Sarah conducted 40 user interviews in six weeks. She didn't just collect feedback - she identified a pattern we'd all missed: users weren't confused by the interface, they were confused by the data model. Her redesign reframed the entire product around user workflows rather than database tables. NPS improved from 12 to 47 in one quarter. What sets Sarah apart is her ability to lead without authority. She was the PM on a cross-functional initiative spanning engineering, design, and our legal team - probably the hardest stakeholder coordination challenge we had. She ran it like a conductor, not a dictator. The project shipped on time and became our most-requested case study from the sales team. Of the 12 PMs I've managed in my career, Sarah is in the top tier - not just for her product sense, but for her integrity. She's the person who raises the concern everyone else is thinking but no one will say. I give Sarah my highest recommendation without any reservation. She would be an asset to any product team. Please feel free to contact me if I can provide any additional context. [Name] [Title] [Email] [Phone]</example> </examples> <verification> Read the letter. If you were a hiring manager, would this letter make you want to interview the candidate? Is it specific enough that it could only describe THIS person? </verification> Candidate details: [YOUR CANDIDATE DETAILS]
